Texture corrosion liquid medicine

Abstract

The invention provides texture corrosion liquid medicine which comprises 3-9 parts of ferric chloride, 4-15 parts of copper chloride, 5-16 parts of the mixture of hydrochloric acid and nitric acid, 3-7 parts of potassium dichromate, 2-4 parts of picric acid, 5-15 parts of a sodium metabisulfite aqueous solution and 30-40 parts of deionized water. The texture corrosion liquid medicine can corrode various kinds of metal and has the good corrosion effect on common steel, high-strength steel, stainless steel and alloy steel, additional high-temperature heating is not needed, and corroded textures are clear and uniform.

Description

technical field [0001] The invention relates to the technical field of corrosion of metal steel plates, in particular to a texture corrosion potion. Background technique [0002] With the vigorous development of the automobile industry, people put forward higher requirements for the comfort of the car. More and more hard plastic parts are replaced by soft plastic imitation leather. In the production process of soft plastic parts, nickel shell molds It is one of the indispensable molds in its production process. The difficulty and complexity of nickel shell mold manufacturing is very high. The effect of using wood molds for mold making is not good, and the use of wood consumes a lot and damages the environment, so it is selected The metal plate is used for mold making. The metal plate mold needs to etch the texture on the metal plate first. However, in the existing technology, the corrosion efficiency of the corrosion potion is low, and the corroded texture is uneven, and the...

The metal plate mold needs to etch the texture on the metal plate first. However, in the existing technology, the corrosion efficiency of the corrosion potion is low, and the corroded texture is uneven, and there is no corrosion for some special metals. effect, it is very easy to cause the metal plate to be scrapped
